Apple has a vision to create the tablet computer market and makes a precise plan, even component suppliers─ memory and screen are included, which is allowed to launch the ipad at very competitive prices, and also there is no compromise in user experience." Gartner was extremely optimistic about the future of the tablet computer. Last month,another research firm In-Stat made a report, estimated the sales of the tablet computer are unlikely to reach 250 million units until 2017. If the company's projections prove true, so Apple iPad and Android devices will include occupy the tablet computer market of 90%.

Microsoft will sell approximately 4.3 million next year, its sales will rise to 34.4 million units in 2015.
